[SOLVED] Confusing errors after update of espressif32 core

miq19 · May 1, 2024, 1:33pm

I today updated the espressif32 core to 6.6.0. After that I got several unexpected error messages when compiling unmodified code I cannot resolve any more.

First was a set of compiler errors mentioning loop() and setup() being not resolvable.

Did a clean
Next was some error about multiple cores on the system, so I tried to do pio run -t clean in a terminal.
Now pio was not found, suggestion was to do sudo apt install platformio
So I did, but when running the pio run -t clean again, I got this:

$ pio run -t clean

What?!?

[Update] Did an uninstall of core version 6.6.0, reinstalled 6.5.0 (that I had before), but the errors are remaining.

Never mind… The problem sat in front of the keyboard, as ever.

I had the path wrong to the main.cpp containing the loop() and sketch() functions. Note to myself. “bridge” is different from “Bridge”…
